ATTACHMENT A LIST OF ENCLOSED INFORMATION Revised response to Q005.3 (SER Confirmatory Item 10)

Revised response to Q40.120 (SER Open Item 14)

New responses to" Questions 321.15 through 321.41, 321.43 and revised FSAR text (SER'Open Item 15) 3648N

BYRON-FSAR QUESTION 005.3 "As noted in Section 5.2.1.1 of the FSAR, the control valves for the Byron Station Units 1 and 2 are not in conformance with 10 CFR Part 50, Section 50.55a, Codes and Standards.

These components are constructed to Section III, Class 1, of the ASME Boiler and Pressure Vessel Code, 1971 Edition, through the Summer 1972 Addenda, whereas, the regulation requires the components to be constructed to the same code and edition through the Winter 1972 Addenda to the code."

"In order to assess the acceptability of these control 9

valves, identify those portions in the 1972 Winter Addenda to the code with which the control valves are not in compliance."

RESPONSE

As stated in Subsection 5.2.1, the Byron control valves are designed and fabricated in accordance with ASME Code Section III, 1971 Edition through the summer 1972 Addenda.

Westinghouse believes that an acceptable level of quality and safety in the design and fabrication of these valves has been achieved by conformance with the Summer 1972 Addenda of the Code, as demonstrated in new Table 005.3-1.

In the unlikely event that some condensation occurs when the turbocharger purging air cools to ambient temperature, the line filter l

in the air start piping, located between the air start valve and air distributor, will collect the moisture.

(Based on ambient conditions of 120' F and 100% humidity, only 0.09 ounces of moisture can be theoretically condensed inside the approximately 50 feet of 2 inch diameter air start piping.)

- In addition, the filter contains a sight glass to show any 5

i Starting Air' Controls Air-applied to the starting air control valve is blocked but flows out an alternate port through a check valve to the manual control air valves.

If all four shut-off valves are open, control air flows through the shuttle valve to the engine controls and shuts down and through filters to the interlock valves.

If the turning gear is disengaged, these interlock valves are open and air flows to the solenoid valves.

If these solenoid valves are activated, air flows through them and a shuttle valve, thus admitting air to the distributors and air start valves in each-cylinder head.

" Describe and justify all Byron /Braidwood VR System design details which differ from those described in AECC-2-P."

4

RESPONSE

There are four major design changes incorporated into the Byron /Braidwood system that were not described in the AECC-2-P Topical Report.

They are:

(1) incorporation of a second venturi scrubber; (2) incorporation of a recycle gas filter for the~ dryer fluidizing air; (3) deletion of the product storage hopper; and (4) modification to the charcoal adsorber.

aDFofgreaterthan10{ngasingleventuriscrubber,provided (1)

The system, utiliz for particulates for a dryer-alone system.

With the incorporation gf the dry waste processor, the DF decreased to less than 10.

The result was a HEPA filter life of only 30 days.

The second venturi scrubber was added to the system to increase the life of the filter.

Tests performed on the AECC system have-demonstrated DFs 4

in excess of 10 and a projected filter life of 6 months.

The secondary scrubber uses condensate as the scrubbing liquid.

Formerly, the concentration of total solids in the condensate was 150 ppm; it has now been increased to 250 ppm.

( 2)'

Extensive testing using recirculated exhaust gas as fluidizing air for the dryer has shown that a potential problem involving an increasing pressure drop across the air distri-bution plate in the dryer exists.

Eventually, this pressure drop will inhibit the efficient operation of the system.

The incorporation of the HEPA filter in this line extends the operation time of the dryer to more than 1 year between maintenance periods.

Normally, the system is decontaminated yearly for maintenance and inspection, and the filter is flushed clean by the standard decontamination procedure which does not increase in decontamination solution quantities.

(3)

Due to height limitations in the building, the inte. face with the packaging system has been modified so that the i

product storage hopper is included as part of the packaging system.

(4)

The depth of the charcoal adsorber has been increased from 6 inches to 11-1/2 inches to provide longer operating life for the adsorber and a better DF for iodine.

One minor change has also been incorporated into the system.

B/B-FSAR The liquid waste feed filter has been relocated from the inlet of the scrubber /preconcentrator to the inlet of either l

of the waste liquor storage tanks.

This will have no effect upon the operation of the VR system since this filter's purpose is to minimize the size of suspended solids in the waste feed.

The filter was moved from the VR system area to the evaporator area to minimize the distance the backflush slurry would have to be transferred.

Topical Report AECC-2-P only provides values for 25%

~

1

RESPONSE

The feed rate of a solution containing just 4% weight boric acid is approximately 84 gph; however, AECC does not recommend

. that a feed solution with a solids concentration of less than 7% weight be sent to the VR system.

If a low concentration slurry was'sent to the VR system, it would have to be processed by the system under manual rather than automatic control.

This would increase the need for operator attention and the operating time'of the equipment because of the larger j

Specify the flow rates associated with decontamination solution to each piece of equipment.

If appropriate, include a discussion of the impacts of periodic decontamination on the liquid effluent source terms."

4 RESPONSE.

'SinceLthe salts generated by the VR system are extremely water soluble, the primary decontamination solution is hot water.

In general, the fluidized bed dryer, the gas solids separator, and the bed storage hopper must be decontaminated at-the same time to prevent the possibility that water might infiltrate into these components through leaky valves and partially hydrating the salts.

This hydration would form hard crusts which are not easily detectable.

To preclude i

this potential, all of these components are thoroughly decon-I taminated as a unit.

The test units have been decontaminated with 500 to 700 gallons of hot water.

No visible evidence of salts in the vessels was evident after the washing.

The decontamination water from this equipment is transferred to the flush water recovery tank..

The pump skids can be.

independently decontaminated by using about 25 gallons of water.

This decontamination water is discharged to the rad' waste building's floor-drain system.

The scrubber preconcentrator can be decontaminated by using about 25 gallons of water.. This decontamination water is transferred to.the waste liquor storage tanks for reprocessing.

The secondary scrubber and condenser are decontaminated as a unit due to close coupling of the piping.

Under normal operating conditions, the liquid in these units contains only 200 to 300 ppm solids and the units cannot be extensively contaminated.

However, if decontamination is required, approximately 100 gallons of water will be required.

When the VR system is decontaminated for the yearly' inspection and maintenance, this 100 gallons of decontamination fluid is used as a first wash for the scrubber preconcentrator.

Consequently, only a total of 200 gallons of water is required i

L to wash the scrubber preconcentrator, secondary scrubber, and condenser.

" Based upon the liquid flow rates presented in Drawing 1190500, the flow rate of liquid from the waste liquor storage tanks is 58 gph to the venturi scruhber.

Stream NN is overflow to the evaporator at a rate of 50.2 gph.

Since only 8 gallons are actually being volume reduced per hour, discus the impact of this additional liquid load on your liquid radwaste system and the impact on the amount of time the VR system is anticipated to be operating."

RESPONSE

Drawing 1190500, Revision E, indicates that the flow rate of liquid from the waste liquor storage tanks (Stream AA) to the venturi scrubber is 56.3 gph.

Stream NN overflows to the evaporator at a rate of 43.6 gph.

However, all of the incoming liquid waste is being volume reduced.

The resulting salts are immobilized and transported to a burial site.

The overflow to the evaporator (43.6 gph contains only 0.02 weight percent solids (200 ppm) whereas the incoming liquid waste stream contained 10 weight percent solids.

The overflow to the evaporator represents an additional liquid load on the radwaste evaporators of approximately 0.73 gpm.

This represents a minimal impact on the radwaste evaporator (0.02 weight percent solids) would result in 10 weight percent evaporator concentrates being produced at a rate of 0.1 gph.

This quantity of waste would have minimal impact on the amount of time the VR system would have to operate.
